UA-135H • Part No. 4025470 • Serial No.________________________________
Dehumidification
The highly efficient Ultra-Aire 135H dehumidifier utilizes refrigeration
to cool the incoming air stream below its dew point. This cooled and
drier air is used to pre-cool the incoming air stream resulting in a
significant increase in overall efficiency. After the pre-cooling stage,
the processed air is reheated by passing through the condenser coil.
The heat removed by the evaporator coil is returned to the air stream,
resulting in an overall temperature increase of the air leaving the unit.
The Ultra-Aire 135H is controlled by 24 volt remote wired controls. A
variety of controls are available suitable to various applications.

Fresh Air Ventilation
Optional fresh outdoor air may be ducted to the unit via a six inch
round duct. This provides fresh air to dilute pollutants and maintain
high oxygen content in the air. The amount of fresh air ventilation can
be regulated by a variety of dampers and controls.
Air Filtration
The Ultra-Aire 135H includes air filtration to improve indoor air quality.
A MERV-11 media filter is standard. An optional MERV-14 deep
pleated 95% media filter is available for optimum air filtration and to
reduce potentially harmful airborne particles. If the optional filter is
chosen, the standard filter operates as a prefilter.

    Proper adherence to these instructions is essential to obtain maximum benefit from your UA-135H indoor air quality system. READ AND SAVE THESE INSTRUCTIONS • The device is designed to be installed INDOORS IN A SPACE THAT IS PROTECTED FROM RAIN AND FLOODING.
  • Page 4: Intended Application

    Place the UA-135H on supports to raise the base of the unit approximately 4" above the horizontal floor below it. Raising the UA-135H will help the unit drain with gravity flow. Do not place the UA-135H directly on structural building members without vibration absorbers or unwanted noise may result.

    Only qualified service people should service this unit. 6.1 Technical Description The UA-135H uses a refrigeration system similar to an air conditioner's to remove heat and moisture from incoming air, and add heat to the air that is discharged. Hot, high-pressure refrigerant gas is routed from the compressor to the condenser coil (See Figure 1).
